Detailed description of the invention

[Background of invention]

Field of Invention

The present invention relates primarily to cartons containing pourable or flowable contents, and more particularly to cartons with their own outlets.

[Description of the Prior Art]

Containers used for pourable contents are often supplied to the manufacturer in the form of semi-finished products of appropriate shape consisting of sheet packaging. These containers are filled at the point of packing, filled with the desired contents that can be poured out, and then sealed. Such a container is mainly used when the contents of the container are not used at once.

Various types of cartons with ejection openings are known in the art (eg, US Pat. Nos. 4,684,058, 4,546,884, 4,362,245 and 4,327,833). Some cartons have outlets formed by flap cut lines or cut lines on the carton walls (e.g., U.S. Pat. Another carton is covered with a flap that the ejection opening is torn, and has an ejection opening with precut holes present in the panel that fold down (ie, US Pat. Nos. 1,491,518 and 3,199,761). Most of these cartons are provided with any means for reclosing the discharge port. However, none has provided the consumer with a carton that is easier to open, reseal and reopen than the outlet of the invention.

[Purpose of invention]

It is a main object of the present invention to provide a carton having a discharge port that makes the contents contained in the carton more fluid than conventional designs.

Another object is to provide a carton having a discharge opening that is more easily opened by initial pull than a conventional design.

Another object is to provide a carton having a discharge opening having a resealing position where the discharge opening is fitted.

Another object is to provide a carton having a discharge opening that is easily reopened.

Other objects of the present invention will become clear according to the following description.

Overview of the Invention

The present invention is directed to a carton having a discharge port designed to increase the fluidity of the actually pourable contents contained therein to the outside. The carton is made by a modified carton half product. The carton consists of upper and lower inner and outer flaps, lower left and right inner flaps, front side portions, rear side portions, left portions, right outer flaps and right inner adhesive flaps.

The discharge port consists of a pull tab connected to the hole cover and the hole cover has a reopening tab extending from the pull tab. The hole cover is generally placed on the discharge hole having a trough bottom. More specifically, the hole has a lower portion with a substantially flat bottom with the sides extending outwardly from each end of the bottom at an oblique angle (this trough shape provides a funneling effect of the contents from the carton. The fluidity can be further improved, this shape also makes it easier for the user to control the contents learned from the carton by directing the contents along the center of the ejection hole towards the target point). The pull tab also has a bend line slightly away from the leading edge of the pull tab. This bend line, if used, is located directly in front of the adhesive surface used to hold the pull tab in place.

In use, the semifinished product is assembled by first adhering the inner adhesive flap to the side of the right outer flap (the adhesive flap does not completely overlap the right outer flap; instead the adhesive flap is between 30% of the right outer flap width and In the range of 70%, which minimizes the amount of packaging needed to make the carton of the invention). The bottom (or top) of the carton is then sealed. The lower (or upper) left and right inner flaps are bent inward along their respective cut lines. The lower inner flap is then bent inwardly along its indentation and eventually the lower outer flap is inwardly bent along its indentation and firmly attached to the lower inner flap with adhesive. The carton is then filled with pourable contents and the top (or bottom) of the carton is sealed in the same way. The discharge port is closed in place when the inner adhesive flap portion is bonded to the right outer flap portion.

The pull tab is lifted away from the right inner adhesive flap portion to allow the contents to flow out of the outlet. A pull tab connected to the hole cover pulls the hole cover away from the right outer flap portion, which is attached by the cut line along the upper and lower edges. Such cut lines are usually cut within the range of 30% to 70% of the thickness of the packaging material. The pull tab is bent at the line at the beginning of the hole cover where the reopening notch (which may be a bend line if necessary) is opened. The hole cover itself is bent along the hinge line in contact with the bend line between the front part and the right outer flap part. The displacement of the hole cover falling from the right outer flap portion exposes the discharge hole and the corresponding lower portion of the trough. The discharge hole is defined by the cutout portions in the right outer flap portion and the right inner adhesive flap portion. The right side of the discharge hole including the right angled portion of the trough is directly formed by this portion when the inner adhesive flap portion is bonded to the right outer flap portion.

To reseal the hole cover, the pull tab is bent inward at an angle of no more than 90 ° towards the hole cover. The pull tab is then inserted into the hole and the hole cover is pushed until the top and bottom cutouts are in contact with the right outer flap. After insertion, the pull tab rests on a small ledge formed by the right inner adhesive flap portion.

In order to reopen the discharge port, the reopening notch, which is integrated from the hole cover and extends outward, is pushed outward. As before, the hole cover moves outward and bends along the hinge line. The lid is opened to a sufficient size so that the pourable contents in the carton can be ejected without being disturbed by the ejection opening (this position is only possible after the pull tab has been completely pulled out of the carton and bent outward). The outlet is continuously resealed and resealed until the contents of the carton are completely gone.

With reference to the drawings in more detail, FIG. 1 shows a semifinished die cut form of a carton 1 according to the invention. Several lines between the panels generally indicate folding lines or notches, and are areas in which the carton 1 is folded to assemble the semifinished product into a finished form.

To assemble the carton, the semifinished product 2 is folded along the notches 66, 68, 70 and 52 with the right outer flap portion 26 covering the right inner adhesive flap portion 28. Thus, the free end 72 of the right outer flap portion 26 is located on the same straight line as the fold line 52 of the right inner flap portion 28. The right outer flap portion 26 is bonded to the right inner adhesive flap portion 28 such that the carton takes a substantially rectangular shape. At the same time, the pull tab 32 is attached to the right inner adhesive flap portion 28 by applying an adhesive to the adhesive portion 46.

Referring to FIG. 6, the discharge hole 36 has a trough-shaped lower portion 34, a square side portion and an upper portion. The small protrusion 80 is located on the upper right side of the trough-shaped lower portion 34. In particular, the trough shaped lower portion 34 of the discharge hole 36 has a substantially flat bottom 78 and the bottom 78 has two side portions extending outward from the end of the bottom 78 at a substantially oblique angle. 44 and 80).

Ideally, the two sides 44 and 80 ideally extend outwardly at an angle of 135 ° from the end of the bottom 78. As shown in FIG. 1 above, the discharge hole 36 has a hole in the left outer flap portion 26 and a notch 64 in the inner adhesive flap portion 28 which remain intact even when the hole cover 40 is opened. Is formed by. The entire right side surface of the discharge hole 36 is formed by the notch 64 including the right wall 44 of the trough 34 (the inner adhesive flap 28 must have the same width as the right outer flap 26). Note that the width of the inner flap section is in the range of 30% to 70% of the width of the right outer flap section).

For example, the top of the hole cover 40 and the cut line 60 is located 0.25 inches away from the top of the carton 1. The width of the discharge hole 36 and the hole cover 40 is 0.75 inch. The depth of the trough 34 is 0.25 inch while the height of the hole 36 on the trough 34 is 0.625 inch. The flat bottom 78 of the trough 34 is 0.1875 inches, while the width of each side 44 and trough 34 is 0.25 inch. Shelf 80 has a width of 0.0625 inches.

It is necessary to seal the bottom (or top) of the carton 1 in order to properly fill the carton 1 and to suitably contain a product (not shown) which can be poured into it. This is done by first folding the lower right inner flap 12 and the lower left inner flap 14 inward. The lower inner flap 8 is attached to the lower outer flap 10 that is folded over the right and left inner flaps 12 and 14 and then folded over the lower inner flap 8. Pourable contents (not shown), such as liquid, rice, cereal, and the like, then enter the carton 1 and then the top (or bottom) of the carton 1 is closed.

The upper part is closed by first folding the upper right inner flap 16 and the upper left inner flap 18 inside. The upper inner flap 4 is folded over the left and right inner flaps 16 and 18 and the left and right inner flaps 16 and 18 are attached to the upper outer flap 6 which is folded over them 16 and 18, so that the container Is sealed. The fully assembled carton 1 of the present invention is shown in FIG. The contour of the outlet assembly 56 in its original sealed position is shown in FIGS. 3 and 4.

In use, the pull tab 30 is initially lifted off the inner adhesive flap 28. This lifting off is facilitated by the cut line of the adhesive portion 46, so that when the external pressure is applied to the pull tab 30, about 30 to 70% of the packaging material of the adhesive portion 46 is separated. It is attached to the pull tab 30 by an adhesive applied to the adhesive portion 46 (behind the pull tab 30) of the carton 1 assembly of 30 to 70% of the separated packaging material. The user's effort to lift the pull tab 30 is aided by placing the bend line 32 slightly back to the end of the pull tab 30 and just in front of the adhesive portion 46. This allows the adhesive-free front of the pull tab 30 to be lifted up and grasped more securely before applying the external pressure necessary to free the pull tab 30 to the adhesive portion 46.

The pull tab 30 is directly connected to the hole cover 40 at the line 62 where the reopening tab 42 is open (if necessary, the line 62 may be a bend line). Thus, after the pull tab 30 is away from the adhesive portion 46, the continuous pressure applied over the pull tab removes the hole cover 40 from the left outer flap portion 26 at the cut lines 58 and 60. (Section is shown in detail in FIG. 5). The hole cover 40 is pivoted about an open hinge line 38 that connects with the right bend line 66 as it exits the right outer flap portion 26. In order to pour out the contents from within the carton 7, the hole cover 40 is detached from the discharge hole 36 sufficiently to allow free discharge of the contents (see FIG. 6).

The resealing is performed by pivoting the pull tab 30 inward with respect to the bend line 62 until the pull tab 30 makes an angle of 90 degrees or less with respect to the hole cover 40. The pull tab 30 has an upper edge 74 and a lower edge 76 which are upper and lower holes 36 when the pull tab 30 is slidably inserted into the carton 1 through the discharge hole 36. Abutting the protrusions 80, respectively. The hole cover 40 is pushed inward until it contacts the cut marks 58 and 60 again. The reopening notch 42 also at this time abuts the inner gluing flap 28 and the pull tab 30 is supported by the projection 80 by the lower edge 76. This relationship prevents the hole cover 40 from being pushed in. When this relationship exists, the carton 1 is necessarily resealed (see FIGS. 7 and 8).

Reopening is accomplished by pulling or pushing out the reopening tab 42, which is preferably arched. This causes the hole cover 40 to pivot about the opening hinge 38 to pull the pull tab 30 within the carton 1 area. The pull tab 30 is grasped and bent to the outside when it is completely separated from the carton 1. Thus, the pull tab 30 is designed to prevent the contents that can be poured out from the carton 1 from being discharged outward. This process is repeated until all the contents of the carton (1) are gone.

The discharge port 56 of the present invention can be used for any size carton. The size of the discharge port is preferably limited to the dimensions shown in the embodiment regardless of the carton size. When the ejection opening of this size is used in a large carton so that the free end of the pull tab 30 is positioned away from the edge of the right outer flap portion 26, the notch is right to make the finger accessible to the pull tab 30. The outer flap portion 26 may be cut.

Although the present invention has been described with reference to specific embodiments, it is to be understood that the present invention is not limited to the details set forth in the specification, as this embodiment is for illustrative purposes only.
